And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. Water pollution is the presence of harmful materials in water, such as sewage, dissolved metal, waste from farms, factories and crude oil spilled from oil tankers. It is always convenient to discuss radioactive pollution separately because its nature of contamination is different from other types of pollution. 3. This can be illustrated as follows: Solar energy heats up the surface of the earth and the air around it. Alternative names for radioactive pollution include ‘radioactive contamination’ and ‘radiological … What is radiation pollution? The main radiation hazards in the environment come from ionizing and non-ionizing radiations. Increased air pollution has been identified as a catalyst for enhanced radiation fog in the past, such as during the deadly London Smog of 1952 (Wilkins, 1954). What is radiation pollution? (a) What is radiation pollution ? Radioactive Pollution is the contamination of radioactive pollutants into the environment. Electromagnetic radiation , waves produced by the oscillation or acceleration of an electric charge . The three main types of emissions from radioactive substances are: Alpha Radiation, Beta Radiation and Gamma Radiation. Figure 2 and 3 show how likely it may be for a particular area to experience air quality advisories for fine particle pollution based on short-term (Figure 2) and annual (Figure 3) averaging. Radioactive pollution occurs when there is a presence or depositions of radioactive materials in the atmosphere or environment, especially where their presence is accidental and when it presents an environmental threat due to radioactive decay. Activities such as bathing and washing clothes near lakes, ponds or rivers add nutrients like nitrate and phosphate into the water bodies.This leads to excessive growth of algae… Radioactive (nuclear) pollution is a special form of physical pollution related to all major life-supporting systems – air, water and soil. Both types are harmful to humans and other organisms. 2. Reducing the amount of pollution produced means less waste to control, treat, or dispose of.
